EasyPost's Shipping API is the most flexible shipping solution on the market. Our RESTful API interface makes it easy for your developers to get EasyPost up and running as fast as possible. We've also designed our API to be flexible. We want to fit your specific system requirements and workflows, not the other way around.

Some of the biggest names in retail rely on EasyPost to test or add new carriers, validate addresses, rate shipments, track parcels, run reports, and optimize shipping routes.
